Не удалось загрузить postgis-2.4.so "неопределенный символ: Float8GetDatum"

Только что обновил до PostgreSQL 10.1 на Arch Linux. Создана новая база данных, и я пытаюсь установить postgis, но она дает мне следующую ошибку:

local=# create extension postgis; ERROR: could not load library "/usr/lib/postgresql/postgis-2.4.so": /usr/lib/postgresql/postgis-2.4.so: undefined symbol: Float8GetDatum 

ldd выход:

Насколько я понимаю, «неопределенный символ» означает, что между библиотеками есть некоторая несовместимость, однако я не игнорирую пакеты pacman.conf, поэтому не уверен, откуда взялась несовместимость.
